Description

2-Hydroxypropyl Salicylate is a versatile organic ester derived from salicylic acid and propylene glycol. This compound is valued for its dual functionality, offering both the beneficial properties of salicylates and the solubilizing, emollient characteristics of a glycol ether. It serves as a key intermediate and active ingredient for manufacturers requiring a stable, effective, and multifunctional chemical building block. Primary demand comes from the personal care, pharmaceutical, and specialty chemical synthesis industries.

Application

• Personal Care & Cosmetics: Acts as a multifunctional ingredient in sunscreens, skincare creams, and lotions, providing UV absorption, keratolytic activity, and enhanced skin penetration for other actives.
• Topical Pharmaceuticals: Used in the formulation of analgesic and anti-inflammatory creams, ointments, and medicated patches due to its salicylate-based therapeutic properties.
• Synthetic Intermediate: Serves as a crucial building block in organic synthesis for producing more complex esters, polymers, and specialty chemicals.
• Functional Additive: Employed in industrial applications as a plasticizer, stabilizer, or solubilizer in various polymer and coating systems.
• Hair Care Products: Incorporated into anti-dandruff shampoos and scalp treatments for its exfoliating and anti-microbial benefits.

Quality Control

Our 2-Hydroxypropyl Salicylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, impurity profile, and physical specifications. While not a compendial item, production can be aligned with cGMP guidelines for pharmaceutical applications, and the product complies with major global chemical inventories like REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
